Calculation of Time of Movement and Speed of a Car on the Intermediate Section of the Hump Yard under Tail Wind

Abstract
The dynamics of the car rolling from a hump yard at a railway station is studied in its various aspects. The authors have also touched upon this topic repeatedly (see, in particular, World of Transport and Transportation, 2015, Iss. 6). However, earlier reports lacked estimates of time of movement and speed of a car on the intermediate section of the hump yard under the influence of tail wind of low speed. The published article fills this gap, introduces the results of calculations, mathematical and graphical dependencies enabling to make certain generalizations and conclusions.
